KuroNeko SPC: its Timer Trick function

Shin KuroNeko SPC can play some of first-note-sticking SPCs with its
Timer Trick function. But unfortunately the software is supposed to be
used only under Japanese win32 environment, you will see just garbage

Timer Trick function, press the third button from the right.

On this advanced configuration tab, you can handle Timer Trick function.
First off, you must select one choice from 0xF4 to 0xF7 ( I don't
know what 0xF4 to 0xF7 mean. APU I/O ports? ). Then set Wait value
( 0 to 65535 ). Finally check the box at the top of Timer
Trick section. If the choice from 0xF4 to 0xF7 is right, it sound at
least. When tempo is not correct, change Wait value. Any changes
are not reflected unless the check box is enabled again.
